African Bank Incompetence

I app**** for a loan with African Bank. Completed the entire online process. Chose a pin and password, even received codes via sms. Once completed all of a sudden the website indicates incorrect cell number which is quite absurd as the number entered is my number and it would be impossible for an alternative number as I have never banked or had anything with African Bank. I proceeded to email documentation such as ID and payslip to an email address as on their website as offers were presented to myself in the form of a loan, a credit card or a short term loan. Now I receive an email from this said document email address indicating to whatsapp the documentation which again ridiculous as I've already sent it via email and uploaded it online. Be that as it may I continued to whatsapp and ofcourse the indication is made to download the app and change my mobile number which again I cannot do as it refuses log in of any sort. I refuse to travel to a branch as I work and I do not have time for this ridiculous error on African Banks side. Please fix it and provide me with exactly what the offers showed. I completed the entire application. Right at the end it threw me out indicating cell number error. Impossible and ridiculous. I am highly irritated by this. To top it off I am receiving calls from a cell number that truecaller identifies as a *****ulent african bank number with thousands of spam reports. Please finalize and fix this.
